IMPROVEMENT IN CAR-WHEELS.

Specification forming part of Letters Patent No. 156,080, dated October 20, 1874; application filed August 19, 1874.

To all whom it may concern:

Be it known that we, JOHN FOWLER and J AMES AGAREETT,ofLouisville, in the county of J eft'erson and State of Kentucky, have invented a new and valuable Improvement in Oar-Wheels; and we do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and gures of reference marked thereon.

Figures l and 2 of the drawing are representations of side views of our car-wheel. Fig. 3 is a sectional view of the same.

This invention has relation to car-wheels which are especially designed for street cars; and it consists in a car-wheel having a removable rim or tread, which is secured to the web of the wheel by means of interlocking dovetail flanges and bolts or rivets, as will be hereinafter explained.

The following is a description of our improvement.

In the annexed drawing, A designates the web of the wheel, and c the central eye thereof. This web is surrounded by a flange, (l, having dovetail grooves b and dovetail tenons a, alternating with each other entirely around the web, as shown in Fig. l. B designates the rim or tread of the wheel, which is constructed with a lange, O', having dovetail tenons a, adapted to lit into the grooves b in the web A, and dovetail grooves b., adapted to receive the tenons a on the web.

By means of the tenons and grooves interlooking with each other, in combination with bolts or rivets g, the rim B is rigidly and safely secured to its web, and can be detached therefrom at pleasure with very little labor.

By thus constructing the wheel, when the tread wears until it is useless it can be removed and a new tread substituted; consequently, when the central part or web ot' the wheel is once pressed on the axle, it will not require taking oli' until the axle itself is worn out.

We are well aware that it is not new to make the body and tread of' a car-wheel in two parts, and, therefore, we do not claim such invention broadly; but

What we claim as new, and desire to secure by Letters Patent, is-

In a car- Wheel, the interlocking dovetail flanges and grooves, for the purpose of securing the removable tread to the web of the wheel.

In testimony that we claim the above we have hereunto subscribed our names in the presence of two witnesses.

JOHN FOWLER.
